Fill data in ComboBox from DataTable using Access database

Question

I have a two column table in an MS Access database and want to fill its second column in a ComboBox from where the user can make a selection. I'm using a DataTable to do it. The code is below:

 

private void Form1_Load(object sender, EventArgs e)

{

OleDbConnection connect = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0; Data Source=C:\Users\Anas\Dropbox\C# Projects\2.Database\ClOsODb.accdb; Persist Security Info=False");

connect.Open();

OleDbCommand cmd = new OleDbCommand("select * from Course Number and Name", connect);

OleDbDataReader odr = null;

odr = cmd.ExecuteReader();

DataTable table = new DataTable();

table.Load(odr);

course_Number_and_NameComboBox.DataSource = table;

course_Number_and_NameComboBox.BindingContext = this.BindingContext;

course_Number_and_NameComboBox.DisplayMember = "Course Number and Name";

course_Number_and_NameComboBox.ValueMember = "ID";

connect.Close();

}

 

 However, the problem is that when I run the application, the ComboBox is empty! It doesn't get filled. Can anyone help me and tell me where I am wrong and what should I do? Help will be greatly appreciated.

 

Also, can anyone tell me how will I get the value in the first column of the selected row of the DataTable when a selection is made at the ComboBox(in other words, when an item will be selected in the ComboBox-second column of a row in the table-how will I know which row is selected in the ComboBox and how will I get the value in the first column of the same row)?
